Title: Detecting device
Inventor: INOUE SATORU
IPC: G01M99/00
Filed: 1977-09-26
Abstract: PURPOSE: To eliminate effects of noise signals from signal sources other than the object being measured by separating signals of the object being measured from those of other sources and suspending the inspection for a certain period of time when the signals from other sources than the object being measured exceed a certain level.  
     CONSTITUTION: Signals emitted from the object being measured are converted into electric signals in a sound collector 2, and then fed into a comparator 6 to judge whether abnormal sound or not. When a disturbance noise is generated during measurement, the noise is collected in sound collectors 3a, 3b, and fed into comparators 13a, 13b. If the signal is beyond the reference set level, a pulse signal is generated. Either pulse signals will operate a timer 14 to transmit a pulse signal having a time width to a gate part 7 and a timer 8. While this pulse signal is being generated, the inspection from the sound collector 2 is suspended, which may eliminate the malfunction due to disturbance noise
